MACHINE FOR CUTTING CARD-BOARD.

SPECIFICATION forming part of Letters Patent No. 242,280, dated May 31,1881.

Application filed November 19, 1880.

To all whom it may concern:

Be it known that I, JULES DE BEAUVAIS, of the city, county, and.State-of New York, have invented' a new and useful Improvement inMachines for Dividing Gard-Board, Paper, and Similar Materials, whichimprovement is fully set forth in the following specification.

The invention has for its general object to divide a sheet or web of auy suitable material both longitudinally and transversely at onecontinuous opera-tion, and is more particularly intended to cut singlesheets of card-board or Othercmnparatively stiff material, although itcan also be used in order to sever a web of paper or other flexiblematerial, and to act upon more than one sheet or web at a time. [nsevering several thicknesses of card-board at the same cut a bead is aptto be formed on the edges of the cards, so that they are of inferiorquality.

In the manufacture of postal and playing cards and the best quality ofcards for other purposes each sheet is cut singly, it being firstdivided lengthwise and then crosswise. The rst operation, or slitting,is effected by one or more pairs of rotary cutters or shears, which arecombined with suitable feed-rollers on both sides of said cutters. Thesecond operation is usually performed by operators using smallhand-shears, the strip being held while cutting against a suitable gage.Attempts have also been made to cut a single strip from theslitting-machine into cards by a series of rotary cutters. In eithercase there is difficulty, without greater care on the part of theattendants than they can or are accustomed to give, in holding thestrips to the cutters, so as to make the cuts exactly on the rightlines, thus causing great waste of material. There is also greatdisadvantage attending the number of operations requiredthat is, afterthe slitting or division into longitudinal strips is effected oneoperation for each card, or with the series of cutters for each strip ofmoderate length, is

necessary.

In the present invention these difficulties are overcome, and vthe sheetof card-board, after being slit by suitable cutters,is divided.transversely wit-hout interfering with the continuous operation of thosecutters, and while the several strips are so held as to insure that the(No model.)

severing takes place ou exactly the line desired.

It maybe here observed that in web-perfecting presses for printingnewspapers, and in some other machines, devices have been and are nowused to divide a continuously-fed web or sheet transversely, and also insome large presses for dividing the web into two parts longitudinally.The devices are not, however, adapted to the making of postal and othercards, where each piece or card must be regular and exactly of adetermined size.

This invention consists in mechanism for severing transversely one ormore sheets, strips, or webs of card-board or other material as it isfed forward continuously,in which the transverse shear is, whilecutting, carried forward with the material to be divided, in combinationwith cutters for slitting or longitudinally dividing one or more sheetsor webs into strips, which are then divided by said mechanism.

The invention consists, also, in transverseclit-ting mechanismcomprising, in combination, a reciprocating shear-frame, a fixed and amovable shear-blade, carried by said frame, and one or more cranks andconnections independent of the devices for reciprocating theshear-frame, for operating the movable shearblade, and alsoin theconstruction and combination of parts in the machine, as hereinaftermore fully described, and set forth in the claims.

The transverse-cutting mechanism, comprising the elements enumerated,can'be used in connection with printing-cylinders and other devicesacting upon a continuouslymoving strip or sheet.

In the improved machine the speed is but little or not at all diminishedfrom that of the usual slitting-machines by the addition of thetransverse-cutting mechanism.

In'order that the invention and the manner of carrying it into effectmay be well understood, the same will now be described in connectionwith the accompanying drawings, which form a part of this speciiication.l

Figure 1 is a plan view of a machine for dividing card-board intosquares constructed in accordance with this invention g Fig. 2, aview invertical section; Fig. 3, a view in side elevation, partly in section 5Fig. 4, a partial view in perspective of the transverse shear; andFig.

5, views in front and edge elevation, illustrating the preferred meansfor supporting the movable transverse shear-blade, so as to avoidfriction.

A is the supporting-frame; B B', upper and lower shafts, havin gbearings in said frame and carrying the rotary cutters b b for dividing thesheet into strips C C', two pairs of feedrollers for controlling thesheet in its passage between said cutters; and D, a table for sustainingthe pile of sheets, which are to be passed one at a time through themachine. These parts may be of any ordinary or suitable construction.

E represents an additional pair of feed-rollers, which, like the othertwo pairs, have their bearings in the supporting-frame, and they arerevolved at the same speed as the other rollers.

Between the feed-rollers C and E are placed the transverse cutters orshears F F', F being the upper and F the lower cutter or blade. Both ofthem are carried by a reciprocating sheanfranie, G. This frame, asshown, consists of a plate, g, which moves in guides a attached to Ithemachine-frame, and an upright part, g', which supports the cutters. tisrepresented as operated by a heart-shaped cam, H, on the shaft h, thecam working in contact with anti-friction rollers upon pins g2 orprojections attached to the bar g3. The bar is fastened at one end tothe plate g, and is slotted at the other so as to fit over the shaft h.It is held laterally bythe cam on one side and a collar on the shaft onthe other side.

Instead of making the shear-frame reciprocate in right lines or move inguides, it can be supported on pivots and made to vibrate; but in thiscase the radius should be so great that the arc of vibration does notmaterially depart from a straight line. One or more cams could be used;but with a vibratory frame one cam on each side, arranged rather nearerthe top of the frame than the pivot, so as to avoid as far as possiblejarring action, is preferred.

Of the transverse cutters one is lixed to the frame G, being shown asthe lower cutter, 'attached to theupright g. The other is movable, andopens and closes upon the fixed cutter to sever the material betweenthem. rIhe edge of the upper cutter is formed like a very broad invertedV, so as to giveashearing cut. (See Fig. 3.)

As represented in Figs. 1 to 4, the movable cutter F is fastened to thebars f, which work against the face of the upright g', and are held bythe pressure of springs j", so as to allowa slight yielding to thecutter F. The bent pieces g4, fixed to the upright g', serve as guidesto the bars f, and also carry set-screws f2 for adjusting the pressureof the springsj". In Fig. 5 the bars fare held against the up right partof frame Gr by the action of spring f', attached to the latter throughthe medium of a piece, g, which supports an anti-friction roller, f Ananti-friction roller, f6, is also interposed between the bars f and theframe Gr. lated by the screw g5, and the tension of the springf by thescrewj'z.

The bars fare connected by links if3 with the levers K, pivoted to themachine-frame. These levers are shown as operated in one direction bythe cranks L through the medium of the connecting-rods l, and in theother by the springs M. In practice, however, it is better to operatethe movable cutter positively in both directions for obvious mechanicalreasons. The connecting rods l are slotted at their lower ends, and onlyact upon the levers when the pins on said levers are at the top of theslots.

The upward movement of the levers is limY ited by the stops m,f1xed tothe machine-frame. rFliese stops and the other parts are so'arran gedthat the cutter F is brought to rest after it has risen sufficiently toclear the card-board or other material fed through the machine, and whenthe cranks L have reached the middle of their upward stroke the slots inthe connecting-rod allow the cranks to continue their revolutionunimpeded until the middle of the downward stroke, when the levers areagain depressed. The advantage of this arrangement is that there is nounnecessary movement ot the cutter F. It is obvious, however, that theconnecting-rod Z could be hinged to the levers K, (the springs M andstops m being dispensed with but the cutter F would then he elevatedafter it has cleared the work on the return movement of the shear-frame.

The use of a movable cutter of the form shown, with the edge inclinedfrom opposite sides toward the center and operated in right lilies, asdescribed, is attended with advantages over an ordinary pivoted blade,although this could be used in connection with other parts of theinvention, in that the action of the cuttin g-ed ge on the card-board onopposite sides of the center is balanced, and that less motion, andconsequently less speed, of the cutter is required in severing thematerial in the limited time allowed.

The cranks L are fixed to the arbors L', journaled in the machine-frame.Secured to the top of the upright g of the shear-frame G is a guide, I,formed of upper and lower plates, t t', between which the material to besevered is passed, and by which it is held during the action of thetransverse cutters.

Motion is communicated to the several parts of the machine by means ofgearing-such, for example, as shown in Figs.1, 2, and 3. Power may becommunicated to the cam-shaft h or the lower cuttershafts, B'.

The operation ofthe machine will be readily understood. After it hasbeen set in motion a sheet of card-board or other material is fedbetween the first pair of feed-rollers, C, and passes on between thelongitudinal rotary cutters or slitters b b', thence to the second pairof feed-rrollers,C, through the guide I and be- The outward movementofcutter F is regu!

tween the transverse cutters F F', and through the last pair offeed-rollers, E. As it passes between the rotary cutters b b it is slitinto as many longitudinal strips as there are pairs ot' cutters, plusone. These strips are then acted upon by the transverse critters in thefollowing way: The reciprocation of the frame Gis so timed that thesecutters,when moving forward in the direction of the feed, have the samespeed as the periphery of the feed-rollers, and it is during thisforward movement that they close and sever the material, the operationof the movable cutter or shear-blade being effected by the cranks L andconnecting-rods l, in the manner already explained. During the cutting,therefore, the shears and material to be cut are stationary withreference to each other. After the strips are severed the shearframecontinues to advance at .equal pace with them until the shears open andthe movablevcutter or upper shear-blade, F, has cleared itself from thecard-board or other material. rlhe shearframe then returns and bringsthe shears into position for a new cut.

Modifications may be made in the materials, proportions, and mechanicaldevices employed in the machine without departing' from the spirit ofthis invention.

Having thus fully explained the said invention and the manner in whichthe same is or may be carried into effect, what I claim, and desire tosecure by Letters Patent, is-

1. The combination of longitudinal cutters or slitters and feedingrollers or devices for feeding continuously one or more sheets or websof suitable material with a shear-frame,

transverse shear-blades carried by said shearframe, and mechanism, asindicated, for opening and closing said blades, and for advancing themwhile cutting with a uniform speed corresponding with that of said feedrollers or devices, substantially as described.

2. The combination, with a reciprocating shear-frame, of a fixed and amovable shearblade carried by said frame, and one or more cranks andconnected devices, as described, independent of the mechanism4 forreciprocating the shear-frame, for operating said movable shear-blade,substantially as described.

3. The combination, with a reciprocating shear-frame and transversecutter or shearblade fixed thereto, ofa m ovable cutter or sh earbladeworking in guides on said frame, links connected with said movablecutter by means ot' hinge-joints, and mechanism, substantially asdescribed, for raising and lowering said cutter or blade through saidlinks, substantially as described.

4. rlhe combination'of the movable shearblade with bars or guide-piecesto which said blade is attached, the upright to which the iixed blade issecured, the spring, the antifriction rollers, and the adjListing-screws, substantially as described.

In testimony whereofI have signed this specification in the presence oftwo subscribing Witnesses.
